What This Filter Is and Where It Lives
This is the diesel particulate filter canister that sits in the exhaust stream after the DOC, catching soot so your truck isn't rolling coal down I-5. It's a welded steel can with a ceramic substrate inside, and on these Volvo/Mack platforms it bolts in as part of the aftertreatment stack ahead of or integrated with the SCR box depending on model year.
Fitment runs across Volvo VN/VNL and Mack Pinnacle/Anthem trucks from roughly 2000 through 2024, but that's a wide net — engine family and emissions cert year matter more than the truck badge on the hood. A 2012 D13 setup is not the same can as a 2020 D13, even if both trucks look identical from the driver's seat.
The 21716414 and 8AI002 numbers both point to the same physical part — one's the Volvo/Mack parts number, the other's how it's cataloged on the aftermarket side. Same filter, different paper trail.
Why All Those Numbers Cross and What to Check
Volvo and Mack share engine platforms and a lot of aftertreatment hardware after the merger, which is why you'll see numbers like 23108408, 22936980, and 7421716414 all pointing at the same or functionally identical canister. Superseded part numbers pile up over the years too — Volvo revises a bracket or a sensor bung and issues a new number for what's otherwise the same filter body.
Where this gets you in trouble: inlet/outlet flange size, overall canister length, and where the differential pressure sensor ports are drilled. Two DPFs can look like twins on a shelf and have the sensor bosses in different spots, which means your pressure sensors won't line up and you're pulling the thing back out. Substrate cell density also varies by emissions cert year — get that wrong and you'll fight regen faults even though the filter physically bolted in fine.
Bottom line: don't buy off the truck's model year alone. Pull the number stamped or tagged on the DPF you're taking off, or better yet get the VIN and let us run it. That's the only way to know for sure which of these numbers actually applies to your unit.
Ordering From PartStop
We stock 8AI002 here in Tacoma and it's usually a same-day pickup if you're local — nobody wants a truck sitting because of an exhaust part. For everybody else, we ship nationwide and can get this out same day if you order before cutoff.
This unit comes with the standard 6+ month warranty we put on our aftermarket DPFs. It's not a lifetime promise and we're not going to tell you it's a drop-in guarantee sight unseen — confirm your old part number or VIN with us first, then we'll get you the right filter instead of a return shipment two weeks from now.
If you're not sure what you're pulling off the truck, snap a photo of the tag and call the counter. Cheaper for everybody than guessing.
8AI002 Cross-Reference & Interchange Numbers
These manufacturer and aftermarket numbers commonly cross-reference to 8AI002. Use them to identify the part — then confirm the exact fit by VIN or the number stamped on your old unit before you order. An interchange is a starting point, not a fitment guarantee.

Frequently asked questions
Does 8AI002 fit my 2015 Volvo VNL with a D13?
Likely, but 2015 D13 emissions certification had a couple of running changes depending on exact build date. Give us the VIN or the number off your old DPF tag and we'll confirm before you order — cheap insurance on an $899 part.
Is this the same as the Volvo 7421716419?
It crosses to the same filter family, yes, but 7421716419 is one of several superseded Volvo numbers tied to this canister. Physical dimensions and sensor port locations should match — confirm against your old part number since Volvo's revised this a few times over the years.
My truck's derated and throwing a soot load code — is the DPF definitely bad?
Not necessarily. Could be a plugged filter needing a forced regen or professional bake-out, a bad differential pressure sensor, or the DPF itself cracked/failed. Pull it and inspect before you drop nine hundred bucks on a new one — sometimes it's a fifty-dollar sensor.
Not sure it fits? We check before you pay.
Run your VIN and we’ll match parts to your exact truck, or call the counter — a person who knows trucks verifies fitment by OEM number before the order ships. No wrong-box returns.
